1. CELLS

2. Definition of Cell
Cells are membrane-covered structures that contain all of the materials necessary for life. They are the building blocks of all living things.
*BRAIN POP - CELLS

3. Cell Theory Every living thing is made up of cells.
Cells carry out the functions needed to support life.
Cells come only from other preexisting cells through cell division.

4. Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell
Nerve Cell

5. Prokaryotic Eukaryotic
Two Types of Cells
Prokaryotic
Eukaryotic

6. Prokaryotic
Do not have a nucleus and other membrane covered organelles.
All Archaea and Bacteria are prokaryotic organisms

7. Eukaryotic Animal Plant
Eukaryotes – are organisms that contain eukaryotic cells (cells that have a nucleus and other membrane covered organelles)
Have a nucleus and other membrane covered organelles
Protist, Fungi, Plants, and Animals are Eukaryotic Organisms
Animal
Plant

8. “Typical” Animal Cell Shape is CIRCULAR

9. “Typical” Plant Cell Shape is RECTANGULAR

10. Cell Parts/Organelles
Found in Both Animal and Plant Cells!!!

11. Nucleus (Plant and Animal Cells)
Membrane-covered organelle that contains DNA and controls all activities within the cell
DNA – heredity material that controls all the activities of a cell

12. Cell Membrane (Plant and Animal Cells)
Outer layer of cell that allows needed materials to enter and leave a cell

13. Cytoplasm (Plant and Animal Cells)
Cellular fluid surrounding a cell’s organelles

14. Ribosome (Plant and Animal Cells)
A small organelle in which proteins are made from amino acids

15. Mitochondria (Plant and Animal Cells)
A cell organelle in which food molecules are broken down to make ATP for the cell (ENERGY)

16. Lysosome (Plant and Animal Cells)
Digest food particles, waste, cell parts and foreign invaders

17. Cell Parts/Organelles
Found Only in Plant Cells Only!!!

18. Cell Wall (Plant Cells)
A structure found in plant cells that surrounds the cell and provides strength and support for the cell

19. Large Vacuole (Plant Cells)
A large structure found in plant cells that stores water and other liquids

20. Chloroplast (Plant Cells)
An organelle found in plants and algae cells where photosynthesis occurs
Contains chlorophyll – a green pigment in chloroplast that absorbs light energy for photosynthesis
Photosynthesis – the process by which plants capture light energy from the sun and convert it into sugar (glucose)

21. Photosynthesis
Plants Take In - Carbon Dioxide + Water + Light Energy (Sun)
Plants Make - Glucose (Food)
Plants Release – Oxygen
